程序代码：

#include <iostream>

int main( void )
{
    const unsigned coke_price =  29;
    const unsigned soda_price =  17;
    const unsigned amount     = 802;
    for( unsigned coke=1; coke*(coke_price+soda_price)<amount; ++coke )
    {
        if( (amount-coke*coke_price)%soda_price == 0 )
            std::cout << coke << std::endl;
    }
}
